Term Definition
1. Chloroplast A) An organelle that contains chlorophyll in which photosynthesis
takes place.
2. Chlorophyll B) A capacity to do work that can produce physical changes
within living and nonliving systems.
3. Energy C) A green pigment present in all plants that absorbs light to
provide energy for photosynthesis.
4. Glucose D) A type of sugar that is produced during photosynthesis to
store chemical energy.
